Syenite
The DeFi interface for AI agents. One MCP endpoint for swaps, bridges, yield, lending, and risk across 30+ chains.
What This Is
Syenite is an MCP server that gives AI agents everything they need to interact with DeFi — swap routing, cross-chain bridges, yield intelligence, lending rates, risk assessment, and position monitoring. Intelligence and execution in one place (not swap-only).
Agents read data, get quotes, and receive unsigned transactions ready to sign. Syenite never holds private keys — no custody, no API key required, rate-limited for production use.

Architecture
Agent → syenite.ai/mcp
├── swap.quote → Li.Fi API (1inch, 0x, Paraswap, bridges)
├── swap.status → Li.Fi status tracking
├── yield.* → On-chain data (Aave, Lido, Morpho, Yearn, Ethena, Maker, ...)
└── lending.* → On-chain data (Aave v3, Morpho Blue, Spark)
Swap routing via Li.Fi aggregation. Yield and lending data sourced directly from on-chain contracts via Ethereum RPC with Chainlink price feeds.
Yield Sources
- Lending Supply: Aave v3, Morpho Blue, Spark
- Liquid Staking: Lido (stETH/wstETH), Rocket Pool (rETH), Coinbase (cbETH)
- Savings Rate: Maker DSR (sDAI)
- Vaults: MetaMorpho (Steakhouse, Gauntlet), Yearn v3
- Basis Capture: Ethena (sUSDe)
Supported Chains (Swap/Bridge)
Ethereum, Arbitrum, Optimism, Base, Polygon, BSC, Avalanche, zkSync, Linea, Scroll, Gnosis, Fantom, and 20+ more.
How Execution Works
swap.quote returns an unsigned transactionRequest with optimised calldata. The agent or user signs and submits from their own wallet. For cross-chain bridges, swap.status tracks progress. Syenite never holds keys.
Product Tiers
| Tier | Who Operates | Who Custodies | Target |
|---|---|---|---|
| LISA | Client signs | Client's custodian | Institutions wanting self-service lending |
| MLISA | Syenite operates | Client's custodian | Institutions wanting managed lending |
| ML | Syenite operates | Syenite's custodian | Full-service managed lending |
All tiers share the same vault infrastructure (Safe smart accounts + Zodiac Roles).
Distribution Channels
- MCP DeFi Router — the canonical tool interface for AI agents. Free data drives adoption; execution tools generate revenue via integrator fees on swap/bridge volume. Live at syenite.ai/mcp.
- AC Smart Accounts — whitelisted adaptor on Threshold institutional UI.
- Direct Platform — institutions use Syenite vaults directly (LISA/MLISA).
- B2B Infra — lending desks integrate vault API + risk framework.

Status
MCP server is live at syenite.ai with swap/bridge routing (30+ chains), yield intelligence (10+ protocols), and lending tools (Aave v3, Morpho Blue, Spark). Vault contracts are a parallel build track.
